Slice / Intersect / Fillet ????

[arkansascontrols]

Can anyone offer advice on a simple method for solving an issue I'm having with a model of Crown Molding. I have attached a sample of the issue. The molding is all in the correct planes and at the correct angles. I want the three pieces to be aligned and simulate the actual Miter cut that is required to join the pieces without actually combining the solids in the drawing so that I can have an exploded view of each piece with dimensions.

 

Intersect of course leaves me the Miter itself without the molding, I'm sure there is a way to accomplish this I just seem to be having a brain fart at the moment.

 

Regards

I would use slice for this.

 

First draw a 45 degree line in plan view across your miter line.

 

Extrude the line to create a surface.

 

 

Scale the surface if needed to cover all solids.

 

Slice using the "Surface" option keep or remove the desired sides if you wish.

 

Now you should have 2 separate solids.

Many thanks, that did the trick

Not to take away from kencaz, because his help does do the trick but your approach is all wrong.

 

Draw the 2D profile section of the crown molding, then draw a PLINE to represent the "path". Then use the EXTRUDE command and use the PATH option. This will take many unnecessary steps out of your current procedure. Hope this helps

Thanks StykFacE, I am aware of this method, however, Since this was after the fact, I suggested slicing it.

 

Also, he wanted 3 separate sections and extruding would have resulted in a single solid. Either way he would have had to slice it.

I figured you were, like I said I wasn't trying to take anything away from you at all. Just thought I'd throw it out there in case he's new to 3D.

That's why we are all here right... To help each other find different solutions for solving problems. By all means if you see a better option for doing something, fire away.

Hi Guys

 

Usually extrude to path works fine but I have had some instances where the profile I wish to extrude follows path but is offset. I.e. LWPoly around door as path. Start extrude with corner of profile on end of poly goes up & across ok, but offsets on "down". I have worked around it by changing position of path relative to profile, ie moving it midpoint of a profile or even sometimes placing profile at the last vertex of path and extruding in the opposite direction. Is it just me or is this a AutoCAD quirk? This has occured in AutoCAD Architecture 2008 and MAP 2008.

 

Thanks

use the 3DPOLY command instead. This will allow the path to be followed in all 3 axis and not just X,Y.

Thanks StykFacE for tip, will try it next time.
